Debuting her much anticipated 2009 spring collection this past week during the Mercedes Benz Fashion Week in L.A., Lauren Conrad has revealed her passion to do a lingerie line. She shared her desire to Entertainment Tonight, admitting, "I've always wanted to do lingerie."

In an interview with the media, Lauren said, "I would do a sleepwear line. I love going sleep in something pretty. I like clothes even when I am sleeping!" Nevertheless, she didn't disclose further on the planned lingerie collection.

Speaking about the spring collection of her fashion line, which is named after her "Lauren Conrad", she described, "I wanted to go girlie. I wanted it to be springy, so we did big floral head pieces, ruffles and constructed volume."

Aside from her designing career, Lauren is still filming her hit TV series "The Hills." She, in the meantime, is also committed to PR firm People's Revolution. Aside from those commitments, she's having busy days serving as the spokesperson for Avon and writing three-book series, a young adult fiction version, which will be titled "L.A. Candy" and be loosely inspired by her transformation from common teenager to reality TV star and fashion designer.

Her book deal with HarperCollins was announced last month. The first book of the series will be published in the summer of 2009.
